Vertical Centrifugal Pump - Mv Series

C.R.I MV Series Vertical multistage in-line centrifugal pumps are axial suction & radial delivery non-self priming pumps available in various capacity, types of MOC and port connections to best suit the applications. As the suction and discharge ports of these pumps are in the same horizontal axis, this system ensures one pipe horizontal installation and compact pipe connections using the same pipe dimensions. The impellers, diffusers and shaft of these pumps are made up of AISI stainless steel and designed to deliver best possible hydraulic efficiency.

These pumps are powered by a C.R.I. totally enclosed fan cooled, A.C induction motor, suitable for continuous duty. Motor stator is made of low watt loss steel laminations assembled under pressure and rigidly locked in the frame. Dynamically balanced rotor ensures vibration and noise free operations. Shaft is made of quality steel, precision ground of ample size for transmitting the rated Horsepower. All single-phase pumps are incorporated with thermal over load protector. These pumps require an adequate motor protection control panel.
